I've beaten all the levels, so if you need help with a particular one just leave me a shout. As for 129, focus on getting oxygen. Don't bribe the guard; swim around him.
Mulligan system has a bug. I placed a King on an Ace and used the King on a grass Queen. I realized I could have picked up a different Queen, so I clicked on Mulligan. The King went back where it used to be on the board, but the Ace just disappeared!
That last level got so repetitive and frustrating with no checkpoints that I just raged quit. Please add a checkpoint, at least in that open area past the collapsing ceiling. Also, I've noticed that the respawner can fall through thin platforms at high speeds, though very rarely.
If you click on a monster that you already killed, a red number will appear that provides the same info as the regular white numbers. Click it again to change it back to the monster. + if this helps.
A couple of problems: 1) Platforms (especially in the recently added levels) sometimes push you
through walls. 2) Is it just me or is there a memory leak? This game makes my browser lag and eventually hang or crash whenever I restart levels a lot. Other than that, great game 5/5
This game is much improved over the first 5/5
@bomer5: The key is an incredibly rare bonus drop. Equip the Fiery Amulet to increase your chances of getting it.
